ToaZZ whom t mayco'ncern:

Be it known 'that I, FOREST DnrwiLnR, a citizen of the United'States,'residing at I Chicago, inthefcounty'of Cook andl State of Illinois, have invented certain new and useful Improvements in Cooking Apparatus,

` of which the following is a specification.

This invention relates to improvements in cooking apparatus designedfor the use of fluidv fuel, and-one'of .the objects of the same i5 the apparatus, and'by the heat o-f a single burner, and meansy whereby the lburner may be shifted toperformfstill another cooking operation.

A further object is to provide an improved device of this character having means whereby the circulation of the products of combustion from the burner may be readily controlled. f j

To the attainment of these ends, and the accomplishment -of other new and useful objects as will appear, Vthe invention consists in the features of vnovelty in substantially the construction,combination and arr-angel' nientof the several parts, hereinafter more 3o fully described and claimed and shown in the accompanying drawings illustrating ythe -invention, and in whichy Figure 1 is a vertical longltudinal sectional view of an improved device of this 85 character constructed 1n accordance with the principles of this invention.

FORES'Il V. DETWILER, OF CHICAGO, ILLINOIS.

Aof a modification showing the mannerin v forming a chamberl having a laterally eX- tended portion 1G, the walls 17 and the base 18 of the laterally eiitended portion being constructedin any suitable manner and of heat insulating material. The top 19 of the stove Ais constructed of heat insulating material andisjprovided with the usual stove openings 20, and a heat distributer or deflector 21 is supported by the top 19 above the burner 22, so that the products of combustionfrom the burner will strike the deiiector and will be distributed to the stove holes.

The: portion'l of the stove is provided with air inlet" openings 23 controlled by the dampers 24 by vmeans of which-the supply of air to the burner maybe controlled and sup- .ports 25 are arranged within the chamber 15 for supporting a broiler 26 and a removable element'27. l

The laterally projecting portion forming the chamber 16 of the stove proper is provided with an outlet opening -27 controlled by a damper 28,.(see particularly Figs.'1 and 10), by means of which the products of combustion may pass through the outlet y27 into a flue 2.3a and this flue 28a has communication with a flue 29 leadingf'to an outlet pipe 30, the flues and pipe serving as a means for carrying off the gases.

Arranged within the chamber 16 is an in- .Heetrunalaewondine.2:2,Eig,1Tflfiga3s-clined..irallwor,partition 31 which4 extends upwardly from a point adjacent Athe chamber 15 to the heat insulated wall 32, to form a narrow or restricted outlet 33. This outlet' 33 is controlled byv the damper 3a which is upwardly projecting` wall or portion 36 and this forward edge of the wall may be anchored inany suitable manner such las by means of fastening devices 37. The object of the upwardly projecting wall 36 is to 55v perspective view of the entire apparatus.

prevent any grease or liquid or any foreign Fig. 13 is an enlarged detail sectional view `erably slightly curved as shown, and extends across the communicating passage bctween the chambers, at a point between the stove holes. When it is desired to direct the products of combustion to one Set of stove holes, the damper 38 is positioned as shown in Fig. 1 being controlled from the frontof the apparatus by means of 'an actuating handle 39.

When .it is desired to distribute the products of combustion to all of the stove holes, then the damper 38 is adjusted to the position shown in dotted lines inFig. 1. The burner 22 is preferably of the reversibletype and is also removable, being removably supported inany suitable manner, such as by means of a bearing 40 formed in a partition 41, (see Figs 2 and 3), inthe stove, and also having a bearing in the front wall of the stove. The mixing chamber 43 of the burner into which the nozzle 44 projects, the latter receiving its supply of fuel through the supply pipe 45, is provided with a sleeve portion 46 which extends through the bearing 42 so that the end of the burner 22 may be telescoped thereinto, and a fastenin device 47 secures the parts together. hus when it is desired to remove the burner 22, the fastening device 47 is released, and the mixing chamber 43 moved forwardly4 so as to disengage the end of the burner. Access may be'had to the chamber 15 through'a suitable closure 48 arranged beneath the burner for closing .an entrance to the chamber.

The burner 22 is preferably of a size to extend only part way across the chamber 15 and terminates short of the rear wall 49 of the chambei' and a partition 50 is ar ranged transversely of the space between the )Vithin this chamber 51 is arran ed va water coil 53 and the front wall 54 o thechamber 51 is provided with an entrance opening 55 adjacent the burner 22 and this 'opening is controlled by a damper 56 'controlled by a handle 57 that extends'through the lside of theapparatus.

When it is desired Ato direct the products of combustion into the chamber 51 to heat the coil, the damper 56 is opened and is preferably so arranged that it will extend a short distance over the burner and when it is desired to close the entrance 55 to the products of combustion, the damper 56 is closed.

The rear wall 49 of the stove extends for some distance above the top 19 and a support or shelf 58 may be connected with this side wall 59 restin l12), and the `flue `30 preferably his' wall 32 forms one of the side walls of the lovens that preferably pro-V ject above theV top of the stove, the other f upon an extended por# tion 18 of the cham r 16, and the back wall` 6()l of the oven compartment is offset in a direction forwardly of the wall 49 to form a space within which the flues 28, 29A and 30 are arranged (see particularly Figs. 6 and slight distance abovethe top 61 o' compartments.` This4 compartment is pro.

leading therethrough, preferably two openings and projecting into these openings are projects a l the oven y vided with a front wall 62 lhaving openingsl removablelovens 63, (see particularly 1, 8 andv 11). These ovens are superposed and are of a size somewhat less than the interior of the oven compartment so that when i placedin position there will be formed fiues or passage ways around the ovens and between the ovens andthe respective walls of the compartment.' These 'ovens 63 prefer..- ably comprise a body portion having a foi-, ward extremity 64 separate therefromaxid secured thereto by means of faemng devices 65, and these extremities are provided with flanges 66 that are adapted, when the ovens are'inserted through the respective openings in the wall 66^ to rest fiat against the outer face of the wall, and the ovens are removably secured in position in any suitable manner. such as by means of fastenin devices 67 passing through the rear walls o they ovens and through the rear wall 60 of the compartment. If desired suitable supports 68 (see Fig. 1), may be provided for the lower oven. y

A closure 69 is provided for each of the ovens, and additional fastening deyices 70` (see particularly Fig. 8),' are provided for holding the ovens in 'tion and 'these fas,- tening devices pass t rough the flange \66 and are threaded into a collar 71 arranged in the rear of the wall 62. When it is desired to remove these ovens, all that is necessary is to remove the fastening devices 67, 70, after the closures 69 have been opened and then draw the ovens out.4

The lowermost oven which is su ported by the supports 68, (see Fig. l), orms a flue or passage 72y between its bottom and the wall 18, and also dues or passages 73, 74 between its side walls and the side walls of the oven' compartment, and the upper oven is placed above the lower oven to form a flue or passage 25 between the ovens, ilues or passages 76, 77 between its sides and the sides of the oven compartment and a flue or passage 78 between its top and the top wall 61 of the oven compartment. j

A partition 79 is arranged between the A73, and a iiue 80 is arranged between the wall 59 "of the'oven compartment andthe adjacent wall of the upper oven near the bottom thereofto form a closure for the bottom of the flue 77. rlhis 1ue80 extends entirely across'the passage and has an opening or Ainlet' 81 through its upper wall, which communicates with the flue 77, and this iue -80 has communication by means of a iiue'V 82 arrangedladjacent the back ,wall

60 of the oven compartment',jand outside of j the oven, with theflue or pipe 3Q, as shown opened lclear/ly in Figs. 1 and 6.

'27 and which An outlet opening 83 leads from, the Hue 25 to the iue29 4and this outlet is controlled by the damper 84, similar to the damper an operating handle' 85 arranged at the front of the apparatus.

A damper -86 similar to the damper 34 is provided to close the entrance to the flue 7 6', the ldampers: and 86 being connected by means Aof a link 87 so that when the. -damper 84 is opened, the damper 86 will be closed and vice versa.

The operation of paratus is as followsz'When it is desired to use the stove holes and not the ovens, the damper 34 is closed and the damper y28 so that' the products of combustion will pass out vof the opening 27 'into the flue 28a, damper 84 desired to use the lowermost oven and not the upper-oven, the damper 86 is closed and the damper 84 opened, while the damper 28 is closed and the damper 34 opened. This will cause the products of combustion to flow into the flue or passage 73, thence into the flue or passage 72 under the lower oven, through the Hue or passage 72,' into the flue or passage 25 between the ovens', through the openings 83 into the iue 219 and out of the flue 30. When it is desired to use both ovens, the` damper-"84 is adjusted to close the opening 83 and this will simultaneously adjust the damper 86 to open the passage 76. Then the products of combustion instead of passing through the lopening `83 will iow into the flue or passage 76 through the iiue or passage-7 8 thence into the flue or passage 77, into the flue or passage' 8O through the opening 81, into the flue 82 and thence through the flue or pipe 30. Thus it will be manifest that thecircula-tion of the products of combustion will be at all times .absolutely under the control of the operator.

When it is'desired to employ kerosene as a fuel, the burner 22 may be removed in the manner alreadyA described'and the broiler 26 flue- 29 and the' outlet pipe 30, the

and removable support 27 are also removed,

damper 84.- is'controlled by this portion of the apf being also closed.r When vit is 1 which receives its supply through the pipe 90, the damper 24 controlling the openings 23 being closed. In order to supply air `to this burner 89, there isprovided an inlet 91, arranged in the bottom 92 of the chamber 15, and which inlet is controlled by a closure 93,. thatis adapted to be open for this purpose and closed when the .burner 22 is used. When the burner 89 is not employed, the opening. 94: through which -the pipe 90 passes, is closed by a suitable closure 95.

The entire apparatus may be supported by means of suitable legs 96, and a. suitable support or shelf 98 maybe provided beneath the ovens. 1
